&gt; &gt; dyou mean you need to know the freakin latitude too  well of course ahem<br/>
<br/>
&gt; &gt; it is n46d15m precisely to as many digits of zero as you like<br/>
<br/>
&gt; <br/>
<br/>
&gt; So it&#39;s west-along-that-parallel then?<br/>

<br/>
&gt; <br/>
<br/>
&gt; A loxodrome is a curve which always cuts the lines of longitude<br/>
<br/>
&gt; at the same angle (and is therefore straight on a Mercator map).<br/>
<br/>
&gt; That means a line of latitude is a loxodrome.<br/>

&gt; Does &quot;great circle&quot; need explaining?<br/>

 </span></blockquote>oh no not more great circle explaining<br/>
<br/>
well evidently it does need explaining<br/>
<br/>
so ok <br/>
